1. A pressure gauge attached to a pipe is reading 1.34 m of Hg at a place where the atmospheric pressure is 10.33 m of water. The approximate absolute pressure at the mountain is a 930 kPa b. 181 kPa e. 280 kPa d. 100 kPa 2. The flow is said to be unsteady and non-uniform when, a The flow velocity is not changing with time but changing with space b. The flow velocity is changing with both time and space c. The flow velocity is changing with time but not changing with space d. The flow velocity is not changing with both time and space 3. The below figure shows a pipe with a circular cross section of diameter D mm on the left end and a square cross section with side D mm on the right end. Mercury enters the left end with a velocity 1 cm/s and leaves the right end with a velocity Vz. Find Va (neglect losses in the pipe). a Cannot be find since length is not given b. Cannot be find since diameter is not given e. 7.85 mm/s d. 12.73 mm/s 4. I kg water is flowing through an inclined pipe at inflow velocity of 20 m/s. The pressure at the inlet of the pipe is 200 kPa The total energy at the inlet of the pipe is

system, the driver gear ear's axle by a certain small motor. Hand drills pm) are the number ocity ratio (VR) is abling гор task 2 Calculate mechanical advantage for gears using ratios n your own. rook at the gear train in Figure 15. Driver gear Teeth = 25 90 rpm ar the driver, the has 40 what is 04 cm 012 cm Driven gear Teeth = 75 2. d) b) a) Figure 15 Determine how many times the driven gear will rotate for every full rotation of the driver gear. Use the gear wheel diameter formula. Use the tooth ratio formula to calculate the gear ratio of the gear train. (3) Calculate the output speed of the driven gear. Look at the gear train in Figure 16. Calculate the velocity ratio of the driven gear. Calculate the velocity ratio in revolutions per minute at gear C. Driver gear Teeth = 15 Idler gear Teeth = 45 (4) (3) (3) (8) Figure 16 A B Driven gear Teeth = 5
